To all whom 'it may concern.'

Be it known that I, EBEN R. CHRIs'rEN- snN, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented .certain new and useful Improvements in Wrappers, of which the following is a specication.

The object of this invention is to provide a means for wrapping or protecting bundles which shall be economical of paper and of the time required in the wrapping operation. In the accompanying drawings, Figure 1 is a perspective view of a package of maga.-

zines, the magazines' being protected by means of wrappers embodying the features of my invention. Fig. 2 is a plan view. of one of the'wrappers. Fig. 3 is a fragmental perspective vlew showing a wrapper par.- tially folded. Fig. 4 is a fragmental detail view.

In Fig. 1 the reference letter A denotes a pile of magazines or other articles, the top and bottom portions of the pile being protected by means of wrappers. One of the wrappers B is illustrated in Fig. 2 in unfolded or fiat condition. The wrappers may be of any suitable material, as for example, paper of the necessary strength and lexi ility.A Thepreferred material is not a cardboard, but a tough flexible paper.

Each wrapper B is of rectangular. form, the size and shape of the rectangle depend- .ing,.at least in part, upon the size of the article or articles to be wrapped. Each wrapper is scored, creased or 1n ented along .the lines upon which the wrapper is to be `folded Preferably, the `paper is indented which are arranged to lie at the sides of the pile of magazines.I The grooves 3 and 4 dene corner portions 6 which are adapted to lie at the ends of the pile of magazines. In thellustrated embodiment, each groove 8 is equal te one-lf -thelength of a `groove'2 portions 6 when folded 1nto the position -I shown in Figs. 1 and 3.

The portion of the wrapper between the grooves 2 and 3 at each end of the sheet, is divided by the diagonal grooves 7, thus dividing the portion ofthe wrapper between the grooves 2 and 3 into a diagonal section 8 and two diagonal sections 9 adaptedto be folded to overlie the section 8, as in Fig. 3. When thus folded, the triangular sections 8 and 9 constitute a triangular flap of double thickness adapted to overlie the portions 6, as shown Fig. 1.

If, as hereinbefore suggested, the portions 6 are made of such dimensions as not to abut when in the position shown in Figs. 1 and 3,

'it'will be evident that the sections 9 will the mere drawing of the cord around the' larger sides of the package causes the portions 5 of the wrappers to fold into contact with the sides of the pile,and such folding of the portions 5 causes the portions 6 and 9 automatically to assume the position shown in Fig. 3. Thus when the cord is assed around the ends of the package the triangular flaps 8 are drawn into contact with the portions 6 of the wrappers. No attention need be paid by the'workman to the folding of the wrappers. it is not necessary to tuck the portions 6 against'the ends of the pile of magazines, nor to fold the portion 8 against the ortion 6, .these operations being automatical y effected by the act of placing the cord around the package and drawing the cord taut. A considerable economy in` the time of the workman is thereby effected. Furthermore, the neatness and eectiveness of the wrapping are not rdependent upon the wrappers B may be done by means of anyl 'suitable machine It will beevident that the invention is not limited to the wrapping of iles of magazines, but that any other articles (and particularly those which require protection mainly on two opposite sides) may' be wrapped in the manner herein disclosed.

I claim as my invention:

1. A. wrapper sheet, grooved to define a central area adapted to lie in contact with one end. 0f a pile of articles, tWo opposite side ortions, two opposite end portions dividedJby diagonal lines into three triangular portions, and four rectangular corner por- Y' tions, the corner portions being folded in against the end of the Ipile, and the triangular end portions being folded upon each other to form a flap which is folded against the outer side of said corner portions. Y

' 2. A fiat unfolded rectangular sheet vone face of which is grooved to dene a central rectangular area adapted to lie in contact with one end of a pile of articles, two opposite portions adapted to lie at the sides of the pile, four rectangular corner portions adapted to lie at the ends of the pile, the portions of the sheet lying between said corner portions at each end of the sheet being divided by two diagonal lines into an approximately triangular portion andv two smaller approximately triangular portions adapted to fold upon the other triangular portion to form a tri-angular flap of double thickness adapted to lie in contact with the rectangular corner portions.

In testimony whereof, I have hereunto lset my hand.
